The object of this invention is to facilitate the compression of hay,cotton, straw, moss, and other substances into bales.

In the accompanying drawings, Arepresents the balin g-box, which ismounted upon wheels B for conveniencein moving it from place to place.In an opening in the forward part of the upper side of the baling-box Ais secured a hopper, 0, through which the material to be compressed isintroduced. The forward side,

D, of the hopper O is madeheavy, andis hinged at its lower edge,-so thatit can beturned down to force the substance in the said hopper down intothe baling-box in front of the follower E.

F are blocks of such a size as to fit loosely into the baling-box, andwhich serve alternately as follower-blocks and as head-blocks. Theseparate follower-blocks F are grooved upon vtheir opposite sides forthe passage of the bale-bands, and are bound or faced with Fig. 7,

or other material is packed against it by successive forward movementsof the follower E. The hay is kept from expanding as the follower E isdrawn back by dogs G, pivoted at their middle parts in slots in thesides of the balingbox A, in such positions that their forward ends willbe a little in front of the forward side of the feed-hopper (J. Theforward .ends of the dogs Gare pressed inward by spiral or othersprings, H, connected with the outer ends of the saiddogs G. With thisconstruction the forward ends of the dogs G are pressed outward by theadvance of the hay, and spring inward into grooves in the sides of thefollower E as soon as the hay has passed, so as to hold the hay fromexpanding into the space beneath the hopperO when the said followerE isdrawn back. As the bay for the bale is being packed the block F movesforward through the balechamber and rests against the rounded inner.edges of the metal plates 1, attached to the r sides of the deliver endof the billing-box A.

Upon the outer parts of the plates I are formed lugs, to which arehinged the bars or as shown in Fig. 1, and are held in place by a loop,K,hingedj to one ofthe plates I, and swung over the free end of theouter bar, J. When a sufficient quantity of bay for a bale has beenpacked into the baling-box A a second block, F, is inserted in the rearof the hay and the follower E is pressed forward to compress the hayinto a bale. When the hay has been compressed into a bale of the desiredsize the rear block F passes a second set of spring-dogs, L M, by whichit is held while the bale is being tied, leaving the follower E free tobe used for packing hay for another bale against the rear side of therear block F. When the bale is tied the barsJ J are released, and thebound bale is forced out of the balingbox A by the advance of the rearblock F, as it is pushed forward by the hay.

The upper part, N, of the follower E is made separate, is hinged at itsrear part to the body of the said follower, and its forward part is heldup by spiral or other springs, O, placed beneath it. With thisconstruction, should the follower E begin to move forward before the hayhas passed down from the hopper O, the top piece, N, will yield andallow the surplus hay to lap over the top of the said follower, so as toprevent the forward movement of the follower from being obstructed. Thehay overlapping the top of the follower E is held from being carriedback by the said follower in its rearward movement by hooks P, hinged inslots in the top of the baling-box A, just in front of the hopper (J,and which are held down by their own weight or by weights Q, orequivalent springs, bearing against their upper sides. The points of thehooks P are inclined forward, as shown in Fig. 3, so that they will beraised out of the way by the pressure of the advancing hay, and willtake hold of the hay and prevent it from being drawn back by therearward movement of the follower E.

If desired, the feed-hopper O, the feed-door D, the spring part N of thefollower, and the hooks P, instead of being at the top of the press, canbe arranged at one side, so that the press can be fed from the ground.

The rear side of the follower E is recessed, and in the cavity thusformed is hinged the end of a lever, B, by a belt or pin, S. The middlepart of the leverR is pivoted to the upperend of a small frame, T, thelower end of which is pivoted to the lower part of the baling-boxframeAbyarod or long bolt, U. This construction causes the lever B topress the follower E forward as the rear end of the said lever B isdrawn downward.

To the rear end of the lever B is secured a chain, V, by a link, W, andhook X, or other suitable means. The link W is made with its upper partwide enough to allow the chain V to be drawn through it, and its lowerpart narrow to receive alink of the chain V. The upper end of the link Wis passed through a hole in the rear end of the lever It, to receive ahook or other toggle at the upper side of the said lever B. W'ith thisconstruction the chain V can be readily lengthened or shortened to givethe follower E a shorter or longer movement, asmayberequired.ThechainVpassesaround a roller, Y, pivoted by a bolt or pin, Z, to thelower part of the frame of the balin g-box A, or to bearing-blocks a,attached to the said frame. From the roller Y the chain V passes beneaththe rear cross-bar of the brace-frame b, over the forward cross-bar ofthe said frame I), and its end is attached to the outer end of a cam, c.The cam c has a sleeve or long bearing, (1, formed upon its inner end,to receive and work upon an upright shaft, 0. The shaft 6 revolves inbearings attached to the power-frame f, and to its upper end is attachedthe sweep g, to which the power is applied. The cam c rests upon acircular plate, h, bolted to a spider or frame, z',keyed or otherwisesecured to the lower part of the shaft e. The edge of the plate It isrecessed to receive a curved bar, j, which is pivoted at a littledistance from its forward end to the said plate h. The forward end ofthe curved bar j is pressed inward by a spring, k, to engage with theouter end of the cam cand cause the said cam to be carried around by andwith the plate h and shaft 6 in their revolution. The curved bar j isprotected from the chain V by a guard plate, attached to the saidcam-plate h. The forward end of the guardplate 70 is inclined, so thatthe chain V will pass over it freely.

To the edge of the cam plate h is hinged a loop, I, which'can be swungover the rear end of the curved bar j, to hold the forwardend of thesaid curved bar j out of the sweep of the cam 0 when it is desired tohave the cam-plate it turn without forcing the follower E forward.

m is a rod which works in bearings attached to the upper and lower partsof the powerframef, and which has a crank arm or handle, 12, formed uponor attached to its upper end. Uponthe rod m, directly opposite the edgeof the cam-plate h, is formed a crank or bend, 0. With thisconstruction, by turning the bend or crank 0 of the rod m close to theedge of the cam-plate h, the said crank or bend at each revolution ofthe cam-plate h will press the rear end of the curved bar j inward andrelease the cam c. When it is desired to have the earn 0 carried aroundmore than one revolution, the crank-rod m is turned to take its crank 0out of the sweep of the curved bar 9. The face or forward side of thecam c is grooved to receive and hold the chain V, which groove, afterpassing partly around the hub of the said cam, gradually passes into anupward inclination, so that the chain will pass up to and be wound uponthe sleeve (1.

To the shaft 6, above the sleeve (1, is keyed or otherwise secured asecond spider or frame, 19, to which is bolted a circular cam-plate, q.To the plate q is permanently attached a cam, r, the forward end andouter side or face of which is grooved to receive and hold the chain 8.The rear end of the earn 0" is bent outward and is inclined, so thatwhen the chains reaches the said rear end of the cam r it will slide upthe said incline, and will thus be thrown from the said cam. The chain 8will thus be wound upon and released from the cam r at each rev-'olution of the cam-plate q and shaft 0.

A little in front of the forward end of the cam 4" two parallel cleats,t, are attached to the cam-plate q, the forward ends of which cleats tare inclined, so that the chain 8 will slide over them freely.

To and between the rear parts of the cleats t is hinged the end of asmall plate, u, in such a position that when turned forward it will liebetween the cleats t, so that the chain 8 will pass over the said cleatsit without touching the plate a. When the plate a is turned back itsfree end will rest upon the forward end of the cam r, and serve as aguide to the chain 8, so that the said chain 8 will pass over the saidcam 1' without engaging with it. The end of the chain 8 is connectedwith the shaft 6 by a ring orother suitable means, so that it can playfreelyupon the said shaft. The chain 8 passes between cross-bars of theframe f and bears against a roller, '11, pivoted to the said cross-barsof the frame f, to hold the chain 8 in place while being operated uponby the cam r. The other end of the chain 8 is attached to the followerE, so that the said follower will be drawn back when the chain 8 isoperated upon by the cam 1*.

To the ends of the brace-frame b are attached brackets, frames, orblocks w, torest against the adjacent ends of the frames A f and preventthe said frames from being drawn toward each other by the tension of thechains V s. The chains V 8 cross eachother at the forward end of thebaling-box frame A, and are kept from contact with each other by aguard-plate, w, placed upon bolts or rods attached to the forward end ofthe baling-box frame A. The middle part of the frame bis covered by abridge made in three parts, y z 1. The middle part, a, rests upon theframe 12, and to one of its edges is permanently hinged the part 3 sothat the said parts y 2 can be folded together for convenience incarrying them. To the other edge of the middle part, 2, is detachablyhinged, by

hooks and eyes or other suitable means, the third part, 1, so that thesaid part 1 can be readily detached for convenience in handling andcarrying the bridge. The outer edges of the side parts, 3 1, rest uponthe ground, so

that the horses attached to the sweep y can readily pass over thebrace-frame b. The bridge y z 1 also keeps the chains from contact witheach other when the upper chain, s, is slackened, as the lower chain, V,will be' below the bridge-piece z and the upper chain, 8, will be abovethe said bridge-piece. The upper chain, .9, when taut, will be a fewinches above the bridge 3 z 1, so that the horses can readily step overit.

2 is the feed-table, to the inner edge of which are attached books 3, tohook into eyes 4, attached to the upper part of the side of thebaling-box frame A.

Eyes 4 should be attached to both sides of the baling-boXA, so that thefeed-table 2 can be attached to either side of the said frame A, asconvenience may require. The feed-table 2 is held in a horizontalposition by braces 5, which are hinged at one end to the outer part ofthe lower side of the said table 2, and their other ends rest upon sidebars of the balingbox frame A.

When the machine is to be moved the feedtable 2 is raised to release thelower ends of the braces 5, and is then detached. The braces 5 are thenswung upward against the lower side of the table 2, and the said tableis again hung upon the eyes 4, so as to hang against the side of thebaling-box frame A, with the free ends of the braces 5 projectingupward.

In working the press, one man stands at the rear end of the baling-box Ato tie the bales, fasten and unfasten the locking-bars J J, and

place the blocks F upon the top of the press as they fall from the rearend of the balingbox. A second man stands upon the balingbox A orfeed-table 2, to place the hay in the hopper G as the follower E movesback and forth, and to place the blocks F in the balingbox 0 in front ofthe follower E when enough hay for a bale has been packed. Athird manpitches the hay upon the feed-table 2 from a stack or other place, andalso attends to adjusting the power. When the press is started thecrank-shaft m is turned to bring its bend or crank close to the plate h,and the guide to is turned down between the cleats If, so that thefollower E will be moved forward and back to pack the hay at eachrevolution of the shaft 6. When enough hay for a bale has been packedinto the baling-box A, thefeeder places a block, F, in the baling-box A,in front of the follower E, and the pitcher turns the guideuback againstthe cam 1' to prevent the chains 8 from being operated upon by the saidcam r, and turns the shaft m to bring its bend or crank o away from theedge of the plate h, so that the catchbar j will not be tripped at eachrevolution of the shaft 0, and the chain V will be wound upon the sleeve(1, forcing the follower E forward to compress the hay into a bale. Thebale is tied and forced out of the baling-box in the manner hereinbeforedescribed. When the bale is sufiiciently compressed the pitcher forcesthe free end of the catch-barj inward to release the cam o,- and securesthe said end by a link, I, hinged to the plate h, turns the crank-shaftm into position to trip the catch-barj, and turns the guide a downbetween the cleats t, so that hay for another bale may be packed whilethe preceding bale is being tied, as hereinbefore described.

The framef is mounted upon wheels 7 for convenience in moving the pressfrom place to place.

The frames A f can be provided with separable tongues for convenience indrawing them from place to place, which tongues are not shown in thedrawings.

The chain 8 is made in two parts connected by a book, so that they canbe separated when desired.

When the press is to be moved the bridge y z 1 is removed, and the parts3 z 1 are laid upon. the forward part of the frame f, the chain 8 isunhooked, and the chain V is detached from the lever B. The sweep g isthen turned over the brace-frame I), and the forward end of the saidframe I) is raised until its forward crossbar rests upon the sweep g.The frame I) is then pushed forward until its forward crossbar dropsfrom the rear end of the sweep g and its rear cross-bar passes beneaththe forward end of the said sweep, in which position the said frame I)will ride securely.

Having thus described myinvention, 1 claim as new and desire to secureby Letters Patent- 1. In a baling-press, the combination, with thedriving-shaft ev and the chain V, connected with the lever B, of the cam0, having sleeve d, the spring catch-barj, and the cam-plate h,
